A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. [1] [2] In some applications, each of the large cylinders is filled by a compressor, otherwise they may be filled remotely and replaced when the pressure is too low for effective transfer. The cascade ...
A cascade refrigeration cycle is a multi-stage thermodynamic cycle. An example two-stage process is shown at right. (Bottom on mobile) The cascade cycle is often employed for devices such as ULT freezers. [1] In a cascade refrigeration system, two or more vapor-compression cycles with different refrigerants are used.
A high-pressure area, high, or anticyclone, is an area near the surface of a planet where the atmospheric pressure is greater than the pressure in the surrounding regions. Highs are middle-scale meteorological features that result from interplays between the relatively larger-scale dynamics of an entire planet's atmospheric circulation .

The combustor is fed with high pressure air by the compression system, adds fuel and burns the mix and feeds the hot, high pressure exhaust into the turbine components of the engine or out the exhaust nozzle. Different types of combustors exist, mainly: [3] Can type: Can combustors are self-contained cylindrical combustion chambers.
[3]: 4–5 German physicist Otto von Guericke (1602-1686) invented the vacuum pump, a device that can draw out air or gas from the attached vessel. He demonstrated the vacuum pump to separate the pairs of copper hemispheres using air pressures. The field of pneumatics has changed considerably over the years.
Other lengths are also available. Most low pressure ports are threaded 3/8" UNF, but a few regulators were marketed with one 1/2" UNF port intended for the primary demand valve. High pressure ports are almost exclusively 7/16" UNF. There is no possibility of connecting a hose to the wrong pressure port. [4]: 112
Hydrogen tube trailers are semi-trailers that consist of 4 to 36 cluster high-pressure hydrogen tanks varying in length from 20 feet (6.10 m) for small tubes to 53 feet (16.15 m) on jumbo tube trailers. They are part of the hydrogen highway [1] and usually precede a local hydrogen station.
